What is the primary use of the Trim, RTrim, and LTrim functions?

The primary use of the Trim, RTrim, and LTrim functions is to clean up strings by removing spaces. Specifically, these functions are designed to handle whitespace in string data.

The Trim function removes both leading and trailing spaces from a string, ensuring that when strings are compared or displayed, they do not have unintended spaces that could affect the results. RTrim is used to remove spaces at the end of a string, while LTrim focuses on the spaces at the beginning. These functions are essential in data preparation, especially when dealing with user input or data imported from various sources where inconsistent spacing might occur.

By utilizing these functions, data architects can ensure cleaner, more consistent string data, which is crucial for accurate data analysis and reporting in Qlik Sense.
